WellO2 (styled “WellO2”) is a Finnish-designed respiratory wellness device marketed as a combined steam inhalation and resistance breathing trainer. It is positioned as a breathing trainer for strengthening respiratory muscles, supporting nasal airflow and airway hydration, improving sleep quality (including snoring relief) and enhancing sports performance.

History

WellO2 is manufactured by the Finnish company WellO2 Oy (formerly Hapella Oy). The device was introduced in Finland around 2016 and later made available in international markets including the United Kingdom. According to manufacturer sources, the product has been used by over 100,000 users worldwide.

In 2024 the company gained attention for its research into sleep-disorder applications such as obstructive sleep apnoea.

Technology and Method

WellO2 utilises two principal mechanisms:

• Warm, moist steam inhalation intended to hydrate and open the airways and aid mucus clearance.
• Adjustable breathing resistance during inhalation and exhalation, claimed to train inspiratory and expiratory muscles (a form of respiratory muscle training (RMT)).

The device can be used with a mouthpiece or with a nasal-mask adapter to target nasal and upper airway routes. The manufacturer describes this dual-mode as helpful for nasal congestion and improved nasal breathing.

An optional accessory, the MyBreath™ smart mouthpiece and mobile app integration, is described by the manufacturer as enabling users to monitor breathing strength and track training progress.

Uses and Applications

WellO2 is marketed for several applications within respiratory wellness, sleep support, and performance contexts:

Breathing challenges and nasal congestion

The steam inhalation component is described as helping to loosen mucus, hydrate the airway lining and support nasal breathing rather than mouth-breathing. The resistance breathing element is claimed to strengthen respiratory muscles, which may reduce breathlessness or perceived breath effort.

Sleep issues and snoring

The manufacturer and third-party coverage suggest that improved airway patency, stronger respiratory muscles and better nasal breathing may contribute to improved sleep quality and reduced snoring. Some preliminary research is ongoing in the area of mild to moderate obstructive sleep apnoea (OSA).

Sports performance and vocal/professional use

Because respiratory muscle strength and efficiency can influence endurance and ventilatory performance, WellO2 is positioned for use by athletes, singers, teachers and other professionals who rely on sustained breathing or voice support.

Usage Guidelines

According to manufacturer guidance, a typical session involves:

1. Filling the device with water (manufacturer suggests approx. 0.5 litres) for steam generation.
2. Selecting a steam temperature and adjusting the breathing resistance setting.
3. Inhaling and exhaling through the device (mouthpiece or nasal-mask) for a training period (often cited as 5–10 minutes or longer).
4. Cleaning and maintaining the device per the manufacturer’s instructions.

Scientific and Clinical Evidence

Some controlled studies and pilot investigations have been conducted:

• A study published in Clinical Physiology and Functional Imaging investigated low-workload respiratory muscle training with steam inhalation in patients with stable asthma (n=45) and found improvements: maximal inspiratory pressure (MIP) +21 %; maximal expiratory pressure (MEP) +12 %; vital capacity (VC) +3.7 % over four weeks.
• A validation study of the MyBreath/WellO2-RHM device found high correlations (r≈0.84–0.85) between dynamic maximal inspiratory/expiratory pressure and standard reference devices in healthy young adults, and acceptable short-term repeatability.
• According to the manufacturer’s “Clinical Studies” summary, further studies are ongoing including one on upper respiratory muscle strength training in sleep apnoea.

It should be noted that while early results are promising, many studies are small, pilot-level, commercially linked or not yet peer-reviewed, and the device is not authorised as a medical device replacement for prescribed therapies.

Market and Availability

WellO2 is available in the UK via the official UK website and partner retailers and is distributed in Europe and other regions. The manufacturer claims tens of thousands of users globally; however, independent market penetration and long-term outcome data are limited.

Safety and Precautions

According to manufacturer guidance and independent commentary:

• Users experiencing acute respiratory infection, fever, uncontrolled lung disease (e.g., advanced COPD) or recent thoracic/abdominal surgery are advised to consult a healthcare professional before use.
• The device produces warm steam—users should exercise caution regarding temperature, airway sensitivity and hygiene (especially when sharing mouthpieces or masks).
• Improved breathing performance via a trainer such as WellO2 should not replace clinically indicated interventions for significant sleep apnoea, severe COPD, or other serious respiratory conditions.
